Request to Update Firefox Account Email / Add Secondary Email

Hello Mozilla Support Team, I am reaching out regarding my Firefox account. The email currently associated with my account no longer exists, and I am unable to receive verification codes or reset my password. I would like to request assistance to update my account settings and, if possible, add a secondary backup email to ensure I can access my account in the future. Please add the following secondary email: team@aboveallpersonnel.com I can provide any information needed to verify ownership of the account, including: Approximate account creation date Linked devices Sync history or other identifying information Thank you very much for your help. I look forward to your guidance on how to proceed so I can regain full access to my Firefox account.
